This combo image shows first lady Michelle Obama as she arrives at the Inaugural Ball in Washington on Jan. 21, 2009, left, and Jan. 21, 2013, right. Michelle Obama made it a fashion tradition Monday night, wearing a custom-made Jason Wu gown to the inaugural balls. The ruby-colored dress was a follow-up to the white gown Wu made for her four years ago when she was new to Washington, the pomp and circumstance, and the fashion press.
